PRINTERS CHASE.

Specification of Letters Patent.

Application filed March 30, 1908.

Patented March 2, 1909. Serial No. 424,272.

To all whom it may concern:

'Be it known that I, CHARLES T. DE BRisAY, residing at Ottawa, in the county of Carleton, Province of Ontario, and Dominion of Canada, have invented new and useful Improvements in Printers Chases, of which the following is a speciiication.

My invention which will be hereinafter fully set forth and claimed relates to appliances for locking up type and other printing matter and for holding unmounted plates.

The object of my invention is a chase that is adjustable to the matter which it is desired to use for printing, be it blocks, plates or type or one or more of these combined, locking the matter Without the aid of quoins and furniture. Also for securing plates without the necessity of using blocks specially prepared for that purpose.

Figure l is a face view of my adjustable chase, locking up blocks and type. Fig. 2 is a side view of the same. Fig. 3 is an end view of the same, partly in section. Fig. 4 is a transverse section of the saine, on line 4 4, Fig. 1, and Fig. 5 is a profile of a plate holder.

Afoundation or backing, A, for a plate to be used for printing is made up of sections, 1, 2, 3, 4 and 5; B represents type and C leads, making up a page to be printed... The block A may be in one piece.

-A pair of side bars, D D, of rectangular ci'oss section, plain and of a dep th or height somewhat less than the width or height of a lead or the depth or height of quads is provided. They are preferably plain longitudinally. These are engaged by two end-bars, E E, each made in two lengths or sections and each section left short, so that a free space or gap is left in the center. They are of greater depth or height than the side bars, being about equal in-height to the quads and leads. rThe ends are saddled upon the sides, D, a rectangular opening check or gap, 6, being made near each end which is equal to the cross section of the side bar, open at the bottom and an easy Fit, so that these end bars may slideupon the side bars. Each air is connected by a right and left handed screw, E1,fthreaded into the opposing ends and having a medial angular head, e1, to which a key may be applied. By tightening these screws the side bars are drawn together and tightly clamp the mattei' standing between them.

To hold a plate upon the backing A, plate holders, F, are used, shown separate in Fig. 5. They each consist of a plate shank nearly ype high and having an integral head, j', Hush with the shank on one side but curved at the top and projecting laterally over the other side, the inner face, 7, being beveled downwards and inwards, to iorin a claw with a dovetail hold on the beveled edge of a plate. They may be of any length and one or more may be used on each side, being inserted,

between the side bars and the backing and with or without leads.

Type and other matter. standing in a galley inay be locked up in these adjustable chases and handled and transported with facility and without danger olf being H pied. Their use niakes galleys for standing type unnecessary. They also aiford a cheap and. efl'icient moans for printing from unmounted plates.

I claim as my invention l. In an adjustable chase, the coinbination of a pair of rectaiigulai' side bars", two pairs of end bars oi greater height than the side bars engaging the latter and a right and left handed screw connecting the opposing ends ol each pair of ond bars and having a inedial head substantially as set forth.

2. In a forni holder, the combination ol two rectangular side bars, two pairs of end bars of greater height than the side bars and having openings near the outer ends through which the side bars pass slidingly, a right and left handed screw threaded into the inner or opposing ends of each pair ol end bars and having a medial head, a plato backing adapted to be inclosed within said bars, leads surrounding said backing and a series oi plate holders inserted in said leads and at the sides oi the backing and consisting oll plate sipanks having claw heads adapted to engage the plates, substantially as set forth..

In testimony whereof I have aHixed my signature, in presence of two subscribing witnesses.
